Labcorp Genetics (formerly Invitae), Labcorp RCV001365083 SCV001561318 uncertain significance Epidermolysis bullosa simplex 5B, with muscular dystrophy; Epidermolysis bullosa simplex, Ogna type; Epidermolysis bullosa simplex 5C, with pyloric atresia; Autosomal recessive limb-girdle muscular dystrophy type 2Q; Epidermolysis bullosa simplex with nail dystrophy 2020-01-18 criteria provided, single submitter clinical testing This variant is present in population databases (rs782503404, ExAC 0.05%). This sequence change replaces glutamic acid with lysine at codon 1694 of the PLEC protein (p.Glu1694Lys). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and lysine. This variant has not been reported in the literature in individuals with PLEC-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0").
Ambry Genetics RCV004952824 SCV005471555 uncertain significance Inborn genetic diseases 2024-07-14 criteria provided, single submitter clinical testing The c.5080G>A (p.E1694K) alteration is located in exon 32 (coding exon 31) of the PLEC gene. This alteration results from a G to A substitution at nucleotide position 5080, causing the glutamic acid (E) at amino acid position 1694 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
